RECENT SYSTEM UPDATE

Can you tell me if there is a problem with the latest system update as my console now seems to be of no use.

Saturday it was working fine, Sunday when it started up it resumed the game (PGA Tour 2K21) at halfway through a round when the game was stopped at the end of a round and returned to the menu screen (the console was shut down correctly), then during the
resumed game it crashed with a message displayed saying that there was a 'problem with my saved game data' instructing that it had to be cleared, which I did. Since then I have had problem after problem having to troubleshoot, restoring the console to factory
settings, perform an OSU, I am unable set the console up from the mobile App as it implies that I have entered the incorrect 10 digit code (several times), I have had to do this manually only for it to get so far then unable to sign in, games are not installing
as they are 'stopped' for whatever reason.

I have had numerous error codes: E102 00000C01 8007045D, E105 00000000 8007045D, 0x8007045d. 0x080a40019 and all the time returns me to a screen telling me to either restart the xbox troubleshoot, that is all that I have been doing for two days now and am
a little frustrated to say the least.

If you could help in some way as I am convinced that this is a software issue and nothing to do with the hardware, a problem that is stemming from your end, could this update not be rewound and undone. Please prove me wrong and do something to help myself
and others or I have an expensive ornament to gather dust

Thank you in anticipation
